We turned it into a dramatic play activity with a pizza box that was lying around (excuse the grease spots!). E and I put together a 'house', and then we would call up the pizza parlor (L on the couch) to order a pizza (the girls loved pretending to talk to each other on the phone). L would then drive the pizza over to our house for delivery, where we shared the pizza - yum!
The girls played 'pizza delivery' over and over and over. L noticed that it was hard to share the pizza, so I got her some scissors and she cut it in half to share with her sister:
For the 'pi' part of the lesson, I showed the girls how to take yarn and measure the diameter and circumference of our pizza and then compare them (yep - the circumference was approximately three times the diameter):
Happy Pi Day!
